TO ALL WHOM IT MAY CONCERN:

Be it known that I, J. W. SIMPSON, of' the city of Newark,n tlle countyof Essex, and State of New Jersey, have invented an Improved Catch forWindow-Sash; and I do hereby declare the following to be a full andexact description of the same, reference being herein had to thedrawings that accompany this specification as part of the same. i

The .nature of my improvement consists in the employment of a lever andwedge to hold the sash; also in having a ratch to retain thelever in itsplace.

In Figure l is seen the catch in the window-sash.

In ,Figure 2, the various parts of the catch.

In the stile of the sash, an incline, a, is cut to receive the wedge b,the face oi' the wedge being on a line with the side c of theWindow-frame. A lever-handle, el, has a slotted hole at the eu'd thatpasses through the wedge Zz, through which slot and Wedge a pin is putto connect the wedge and lever. The end of the level' fits in the holee, which is rounded above and below the,lever to allow u. free actionwithout lost motion.` The lever has a pin-fulcrum, f, in the stile ofthe sash. Upon the side of 'the 'hand-end of the lever a is a catch, z',corresponding to the ratch n, on one side of the socket m, the socketbeing inserted in 'the edge of thefstile in a mortise made through thestile to receive the lever d, the ratch and catch being` for the purposeof securing the wedge when tight. I

It will bel seen that in forcing `the wedge between the sash-stile andthe window-frame, the sash can be kept at any desired height.

What 1 claim, and desire to secure, is-

The lever d and wedge 5, constructed, combined, and operatedsubstantially in the manner and for tue purpose hereinabove set forth.

Also the sooketm, with its ratch n, and the catcliz' on che lever d,incombination with the lever and wedge,

in the manner and for the purpose specified` J. W. SIMPSON;
